  • May 27, 2026bird-lg-go is a BIRD looking glass in Go.CVE-2026-45047 · Other software · xddxdd · reported by GitHubHigh 7.5

    bird-lg-go is a BIRD looking glass in Go. Prior to 1.4.5, the apiHandler (and similarly webHandlerTelegramBot) processes user-provided JSON payloads by directly using json.NewDecoder(r.Body).Decode(&request) without restricting the maximum read size. An unauthenticated remote attacker can stream an extremely large, endless JSON payload (e.g., several Gigabytes of padding) over a single TCP connection. Because Go's JSON decoder attempts to allocate memory for the entire parsed structure, this rapidly exhausts the host's physical RAM or container limits, leading to an unrecoverable fatal error: runtime: out of memory. This vulnerability is fixed in 1.4.5.

  • Mar 4, 2026An Argument Injection vulnerability exists in bird-lg-go before commit 6187a4e.CVE-2026-26514 · Other software · Xddxdd · reported by MITREHigh 7.5

    An Argument Injection vulnerability exists in bird-lg-go before commit 6187a4e. The traceroute module uses shlex.Split to parse user input without validation, allowing remote attackers to inject arbitrary flags (e.g., -w, -q) via the q parameter. This can be exploited to cause a Denial of Service (DoS) by exhausting system resources.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
